LEAF TEMPERATURE AND WATER STRESS IN STRAWBERRY
Irrigation enhanced fruit yield and size. The water stress rating by measurement of the leaf-air temperature differential, was correlated to a slightly higher yield than either of the soil-based readings. Maximun yield was recorded at ΔT < 1°C and the minimum with non-irrigated control at ΔT > 4°C. The regressions calculated between the ΔT°C values and the other methods showed a high significant linearity with MET and soil moisture, and poor correlation, with soil water tension values.
